Answer:

(9.5k + 12.7m -0.4n) cm

Step-by-step explanation:

(5.9k+9.3m) + (3.6k−3.9n) + (3.5n+3.4m) = 9.5k + 12.7m -0.4n

Answer: the rate of the water level in the cone falling when it is 5cm from the bottom of the cone is -0.1768 cm/sec

Step-by-step explanation:

Given the data in the question;

H/h = R/r

10/5 = 6/r

r 1 = 30/10 = 3

Also

10/h = 6/r

r2 = 6h/10 = 3/5 × h

Volume = 1/3πr²h

V = 1/3 × π × (3/5 × h)² × h

V =  1/3 × π × 9/25 × h³

V = 3π/25 × h³

Now

dv/dt = 3π/25 × 3 × h² × dh/dt

-5 = 3π/25 × 3 × 25 × dh/dt

-5 = 3π × 3 × dh/dt

-5 = 9π × dh/dt

dh/dt = -5/9π

dh/dt = -0.1768 cm/sec

therefore, the rate of the water level in the cone falling when it is 5cm from the bottom of the cone is -0.1768 cm/sec

Answer: m=13

Step-by-step explanation:

Basically you solve this by finding out what plus 4 equals 17. You can do this by subtracting 4 from 17.

17-4=13

This is how you find the value of m.

Answer:

13!

Step-by-step explanation:

first subtract 4 on both sides!

m+4=17

m+4-4=17-4

simplify/subtract 17-4=13!

Hi there!

[tex]\large\boxed{5n(n + 2)}[/tex]

Factor the polynomial by finding the GCF from each term:

5n² + 10n

Both terms share "5n", so we can factor this out of the expression:

5n(n) + 5n(2)

5n(n + 2)

Step-by-step explanation:

[tex] = 12 + {4y}^{2} - 7[/tex]

[tex] = 12 + {4(3)}^{2} - 7[/tex]

[tex] = 12 + 4(9) - 7[/tex]

[tex] = 12 + 36 - 7[/tex]

[tex] = 48 - 7[/tex]

[tex] = 41[/tex]

Answer:

223.34 m/s

Step-by-step explanation:

Given :

Travel time = 11 :23 pm to 1:00 a. M = 1 hour 37 minutes = (60 + 37) = 97 minutes = (97 * 60) = 5820 seconds

Distance between Seattle and San Francisco is

807.7 miles (culled from the internet)

807.7 miles = 1299867.1 meters

Average speed = Distance covered / Time taken

Average speed = 1299867.1 m / 5820 s

Average speed = 223.34486

Average speed = 223.34 m/s

Answer:

Answer:

Step-by-step explanation:

2) x - y = 2/3

         [tex]x = \frac{2}{3} + y[/tex]

3) 3x +2y = 6

          3x = 6 - 2y

Divide the equation by 3

[tex]\frac{3x}{3}=\frac{6}{3}-\frac{2y}{3}\\\\x = 2 - \frac{2}{3}y[/tex]

4)

[tex]\frac{1}{4}x + y = 2\\\\ y = 2 - \frac{1}{4}x[/tex]

5) 4x - 3y = -33

         -3y = -33 - 4x

Divide the equation by (-3)

[tex]\frac{-3}{-3}y=\frac{-33}{-3} - \frac{4}{-3}x\\\\ y = 11 + \frac{4}{3}x[/tex]

1) Yes, it was easy to solve one variable in terms of the other.

2) Yes, it was easy to solve for y in terms of x. Coefficient of x was a fraction.

3) It will be easy if we take the value of x as multiples of 3

Example: if x = 3,

[tex]y = 11 + \frac{4}{3}*3 \\\\y = 11 + 4\\\\y = 15[/tex]

Answer:

scale factor: 3

Step-by-step explanation:

For this I will take both A and A' points. So A is (2,2) and A' is (6,6) and since the shape increased in size that means our scale factor must be greater than 1. So all that we have to do is know is how did we get from this x value to that x value or in other words 2 times what equals 6 and it's 3. Then we would do the same for the y value but since it would be the same 2 times what equals 6 and it's still 3 so 3 is the scale factor.

Answer:

x=4 and y=2

Step-by-step explanation:

I'm not 100% sure but I substituted different numbers into the equation:

If x=4 and y=2 then 4+2=6 and 3x2=6 so it would be 6=6

Another option is x=7 and y=3 then 7+2=9 and 3x3=9 so it would be 9=9

I'm more confident with x=4 and y=2 because of the small size of the triangle.

I hope this helps! Good luck! :)

OMG, Nickkkkk. It's Nyla from your 3rd block math classs. Lol, I literally looked up this question with no luck of an answer.

Step-by-step explanation:

The school club made $298.08 by selling the balloons.

Profit is calculated as total revenue less total expenses.

Given that, a school club sold 143 balloons for $3.50 each. They bought 150 balloons for $1.29 each, plus $8.92 for shipping.

Cost of balloons when they brought them = 1.29*150 = $193.5

Total cost = $193.5 + (shipping price) = $193.5 + $8.92

Total cost = $202.42

Cost at which they sold the balloons = 143*$3.50 = $500.5

Therefore, their total profit = $500.5 - $202.42 = $298.08

Hence, The school club made $298.08 by selling the balloons

Answer:

$3.00

Step-by-step explanation:

The equivalent value of {x} is equivalent to 2.046.

The cosine function (or cos function) in a triangle is the ratio of the adjacent side to that of the hypotenuse.

Given is the expression as -

cos(47) = x/3

We have the expression as -

cos(47) = x/3

{x} = 3 cos(47)

{x} = 3 x 0.682

{x} = 2.046

Therefore, the equivalent value of {x} is equivalent to 2.046.

Answer:

9 times 800/9 equals 800. (Answer is 800/9)

Step-by-step explanation:

Key skills needed: Equation, Division, Fractions

1) Let's say the number is the variable "x".

2) So this means 9 times x = 800

9x = 800

3) Divide both sides by 9 and you will get x equal to 800/9. If you want this in mixed number form, it is --> 88 8/9

Hope you understood and have a nice day!! :D

88.8888888889

The equation to any of these sorts of questions is the larger number (800) divided by the smaller number (9).

You can check your answer by multiplying the quotient by the smaller number (9). If you get the larger number (800), you were correct, anything else, the equation was done wrong.

Sheldon makes a profit of $8.

The ratio of profit share in a partnership is always constant irrespective of the amount of profit.

Given,

Sheldon makes $2 in profits for every $5 that Leonard makes.

Therefore, ratio of profits of Sheldon and Leonard is 2/5.

If Leonard makes profit of $20

Then,  Sheldon's profit / Leonard's profit = 2/5

           Sheldon's profit / 20 = 2/5

           Sheldon's profit  = $8

Hence, Sheldon makes a profit of $8 If Leonard makes $20 profit.

The Greatest Common Factor of 15 and 21 is 3.

The greatest common factor is the largest number that is a factor of two or more numbers (GCF). The greatest number (factor) divides them, yielding a Natural number. Once all of the number's variables have been identified, there are a handful that are shared by both. The greatest common factor is the largest number found among the common factors. The GCF is often referred to as the Highest Common Factor (HCF)

Given:

We have to find the greatest common factor of 15 and 21 .

So factorizing each number

15 = 3 x 5

21 = 3 x 7
